"When I started, I could do whatever I wanted," said renowned music photographer Henry Diltz. "I was the only guy there with a camera."

Now every fan has one in their pocket, ready to raise it for a concert or a selfie with a star. Anyone can be a rock photographer these days. But being a great one has never been harder.

Diltz -- who has shot iconic photos of the Doors, Jimi Hendrix, the Eagles and Crosby, Stills and Nash (above) -- will tell stories about his life in concert photography when he comes to Ruth Eckerd Hall Friday. He and fellow photographer (and muse to George Harrison and Eric Clapton) Pattie Boyd will give fans insight into the process and artists behind their most famous images.
